Hello, I am aware that this happening because of a9lh because the 3DS will not turn on without it. I have no files except the basic 3DS (Homebrew folder) and the safea9hlinstaller.zip files that have been extracted onto my 3DS. I have no CTRNAND or any backup. When I try to uninstall a9lh it comes up with, 'Error: failed to mount CTRNAND' and when I try to update it, my 3DS says 'Error: firm1.bin doesn't exist or has wrong size.' Please help. 3DS SD card files are underneath btw.
